Background: In December 2019, the COVID-19 outbreak began in China and quickly spread throughout the world and was reclassified as a pandemic in March 2020. The first case of COVID-19 was declared in Togo on March 5. Two months later, few data were available to describe the circulation of the new coronavirus in the country., Objective: This survey aimed to estimate the prevalence of SARS-CoV-2 in high-risk populations in Lomé., Materials and Methods: From April 23, 2020, to May 8, 2020, we recruited a sample of participants from five sectors: health care, air transport, police, road transport and informal. We collected oropharyngeal swabs for direct detection through real-time reverse transcription polymerase chain reaction (rRT-PCR) and blood for antibody detection by serological tests. The overall prevalence (current and past) of infection was defined by positivity for both tests., Results: A total of 955 participants with a median age of 36 (IQR 32-43) were included, and 71.6% (n = 684) were men. Approximately 22.1% (n = 212) were from the air transport sector, 20.5% (n = 196) were from the police sector, and 38.7% (n = 370) were from the health sector. Seven participants (0.7%, 95% CI: 0.3-1.6%) had a positive rRT-PCR test result at the time of recruitment, and nine (0.9%, 95% CI: 0.4-1.8%) were seropositive for IgM or IgG against SARS-CoV-2. We found an overall prevalence of 1.6% (n = 15), 95% CI: 0.9-2.6%., Conclusion: The prevalence of SARS-CoV-2 infection among high-risk populations in Lomé was relatively low and could be explained by the various measures taken by the Togolese government. Therefore, we recommend targeted screening., Competing Interests: The authors have declared that no competing interests exist

Introduction: The extent of neuromeningeal cryptococcosis (NMC) has increased since the advent of HIV/AIDS. It has non-specific clinical signs but marked by high mortality., Objective: To analyze the characteristics of the NMC in sub-Saharan Africa., Materials and Methods: We have conducted a literature reviewed on the NMC in sub-Saharan Africa from the publications available on the basis of national and international data with keywords such as "Cryptococcus, Epidemiology, Symptoms, Outcomes and Mortality" and their equivalent in French in July 2011. All publications from 1990 to 2010 with 202 references were analyzed. The following results are the means of different studied variables., Results: We selected in final 43 publications dealing with the NMC which 24 involved 17 countries in Africa. The average age was 36 years old. The average prevalence was 3.41% and the average incidence was 10.48% (range 6.90% to 12%). The most common signs were fever (75%), headaches (62.50%) and impaired consciousness. Meningeal signs were present in 49% of cases. The mean CD4 count was 44.8cells/mm(3). The India ink and latex agglutination tests were the most sensitive. The average time before the consultation and the hospital stay was almost identical to 27.71 days. The average death rate was 45.90%. Fluconazole has been the most commonly used molecule., Conclusion: The epidemiological indicators of NMC varied more depending on the region of sub-Saharan Africa. Early and effective taking care of patients to reduce diagnostic delay and heavy mortality remains the challenges.

Aims: we measured the burden of TB/HIV co-infection in a rural setting of Benin, and assessed the outcome of tuberculosis treatment at the end of the intensive phase of TB treatment., Methods: This is a retrospective, cross-sectional, descriptive study, covering January 2006 to December 2011., Results: A total of 256 patients were included, 67 (26.1%) were HIV +. A minority, 25% of co-infected HIV / PTB, had TB bacilli high density (+++) versus 45% of mono-infected (P = 0.005). The smear conversion was obtained in 96% of coinfected versus 93% in HIV- at the end of the intensive phase (P = 0.5). The cure rate was 86% and 93.1% respectively in co-infected and HIV-. A proportion of 13.5% of co-infected died versus 3% in HIV- (P = 0.005). 21% of co-infected with CD4 <200 died versus 3.6% of those with CD4> 200 (P = 0.041)., Conclusion: This work underlines the high prevalence of HIV / TB co-infection in this region. Co-infected patients respond well to treatment, but their mortality is high when they are very immunocompromised., (Le comitée de rédaction se réserve le droit de revoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

Background: Infection with Penicillium marneffei is a common opportunistic infection in Southeast Asia where it is endemic. We report a case of Penicillium marneffei infection with fatal outcome in a Togolese woman infected with Human Immunodeficiency Virus (HIV)., Case Presentation: A 45-years-old patient, infected with Human Immunodeficiency Virus had consulted for ongoing febrile pneumonia since two weeks. Clinical examination revealed fever of 38.5°C, dyspnea, pulmonary syndrome condensation and papulo-nodular of "molluscum contagiosum" like lesions located on the face, arms, neck and trunk. Sputum smear was negative for tuberculosis. The chest radiograph showed reticulonodular opacities in the right upper and middle lobes and two caves in the right hilar region. The CD4 count was 6 cells/mm3 after a year of antiretroviral treatment (Zidovudine-Lamivudine-Efavirenz). She was treated as smear negative pulmonary tuberculosis after a lack of gentamicin and amoxicillin plus clavulanic acid response. Culture of skin samples and sputum had revealed the presence of P. marneffei. A treatment with ketoconazole 600 mg per day was initiated. After two weeks of treatment, there was a decrease in the size and number of papules and nodules, without any new lesions. We noted disappearance of cough and fever. The chest X-ray showed a decrease of pulmonary lesions. There was no reactivation of P. marneffei infection but the patient died from AIDS after two years of follow up., Conclusion: We report a case of P. marneffei infection in a HIV-infected patient in a non-endemic country. Clinicians should think of P. marneffei infection in all HIV-infected patients with "molluscum contagiosum" like lesions.

Method: We prospectively studied patients with pulmonary TB, with or without HIV-1 co-infection, from December 1, 2007 to December 1, 2008. Two groups of patients naive for TB and antiretroviral treatment (group A: 96 co-infected TB/HIV and group B: 171 TB infected but HIV negative) were selected randomly. The CD4 count was assessed according to HIV status, and all patients received RHEZ TB treatment for 2 months. Pulmonary smear was assessed at two weeks, four weeks, six weeks, and eight weeks., Result: Two hundred and sixty seven patients were treated (26.6% of admissions). The mean age was 34.62 ± 11 years and the sex ratio was 1.3. A proportion of 35.75% patients were HIV co-infected with a median CD4 count at 157 cells per millimeter cube. The sputum smear conversion was obtained for more than 87.5% of patients in group A and 24.56% in group B at two weeks; 94% of patients in group A and 61.83% in group B at four weeks; 100% of patients in group A and 87.33% in group B at six weeks, and 100% of patients in group A and 96.77% in group B at eight weeks. P<0.05 at six weeks., Conclusion: HIV infected TB patients were more susceptible to treatment than TB/HIV infected patients in the first six weeks., (Copyright © 2011. Published by Elsevier SAS.)

As a follow-up to the first AfroREB (Africa Rabies Expert Bureau) meeting, held in Grand-Bassam (Côte-d'Ivoire) in March 2008, African rabies experts of the Afro-REB network met a second time to complete the evaluation of the rabies situation in Africa and define specific action plans. About forty French speaking rabies specialists from Northern, Western and Central Africa and Madagascar met in Dakar (Senegal), from March 16th to 19th, 2009. With the participation of delegates from Tunisia, who joined the AfroREB network this year, 15 French speaking African countries were represented. Experts from the Institut Pasteur in Paris, the Alliance for Rabies Control, and the Southern and Eastern African Rabies Group (SEARG, a network of rabies experts from 19 English speaking Southern and Eastern African countries) were in attendance, to participate in the discussion and share their experiences. AfroREB members documented 146 known human rabies cases in all represented countries combined for 2008, for a total population of 209.3 million, or an incidence of 0.07 cases per 100,000 people. Even admitting that the experts do not have access to all reported cases, this is far from the WHO estimation of 2 rabies deaths per 100,000 people in urban areas and 3.6 per 100,000 in rural Africa. It was unanimously agreed that the priority is to break the vicious cycle of indifference and lack of information which is the main barrier to human rabies prevention.

Tetanus is still a major health problem in Sénégal. In order to understand some of these reasons, we conducted a study. The aim of this study is to assess ironworkers' knowledge, behaviors and practices about tetanus. This knowledge, behaviors and practices survey was carried out in ironworks of two neighborhoods of Dakar from April 5 to May 10, 2008. 41 ironworks were identified and 32 agreed to participate in the study. In this ironworks, 120 ironworkers were interviewed. Their average age was 29 years +/- 15, education in French schools was low and 78.3% of them had a source of information. Despite some inaccuracies, most ironworkers were aware of tetanus (97.5%), severity (93.3%), causes (89.2%). However 35% did not evaluate the risk of tetanus and almost all the ironworkers or 96.7% had no preventive measures after injury. Moreover, no ironworker was fully immunized against tetanus. In some occupations at risk, awareness of tetanus should be increased by all available channels and methods emphasizing the importance of prevention.

Objective: To determine the effect on clinical progression and mortality during tetanus of intrathecal therapy with 1 500 IU of heterologous antitetanus serum administered with 1.5 g of intravenous metronidazole., Method: This prospective study took place from August 1, 2006, to June 30, 2007, and included two groups of patients randomly allocated to treatment by two different techniques. The test group of 17 patients received 1 500 IU of antitetanus heterologous immunoglobulin by the intrathecal route as well as 1.5 g of intravenous metronidazole daily. The control group of 25 patients received the standard treatment of 9 000 IU of heterologous antitetanic serum administered half (4 500 IU) cutaneously and half intramuscularly. Clinical manifestations and mortality were assessed. Mollaret's classification and the Dakar prognosis score were used to classify patients according to severity., Results: Forty-two patients were treated. Their mean age was 29.44 years (standard deviation: 18.3 years) and the M/F sex ratio was 5. Skin wounds accounted for 57.1% of the portals of entry, deep wounds for 26.2%; the rest were unknown. Twenty patients (47.6%) had fever when admitted. Tetanus was generalized in all cases and 76.2% of patients were stage III. Four patients were HIV-positive. Clinical improvement, defined as a decrease in dysphagia, trismus, and paroxysm, was observed more quickly in the test group: 48 hours after treatment began, improvement was seen in more than 76% of the test group compared with 28% in the control group. In the test group, the mean hospitalization period was 7.4 days and mortality was 11.7%, compared with 19 days and a mortality rate of 52% in the control group., Conclusion: Prevention through vaccination appears to be the long-term solution for the eradication of tetanus. In the meantime, we can hope for a better clinical response with intrathecal therapy of 1 500 IU of heterologous antitetanus serum and 1.5 g of intravenous metronidazole daily.

Objectives: To describe the relation between HIV infection and tetanus., Methods: This prospective study includes all patients admitted to our infectious diseases department with tetanus between July 15 and December 31, 2007, who underwent screening for HIV-1 and 2., Results: The study included 21 patients (sex-ratio = 9.5). Their mean age was 37 years (SD: 5.3) were included. Nine patients (42%) had been immunized, but never received a booster dose. The portal of entry was found in 16 patients (76%) - all but one a skin injury. Tetanus was generalized in all patients (Mollaret classification: 76% Stage II, 24% stage III). Twelve (57%) patients were infected with HIV. Their mean CD4 cell count was 157/mm3 (SD: 75/mm3, range: 74-232/mm3). The overall mortality rate was 53%. It was 100% when no portal of entry was found. It was significantly higher among HIV-positive than HIV-negative patients (82 versus 18%). It did not, however, differ significantly between HIV-positive subjects with a CD4 count < 200/mm3 and those with a CD4 count > or = 200 (58 versus 42%)., Conclusion: HIV and the absence of portal of entry are poor prognostic factors in tetanus. Therefore, a revision of the Dakar International Classification on tetanus should be revised, to score as 1 those patients with HIV infection and no portal of entry.
